UC3852DTR Description

Short technical summary and product information.

The UC3852DTR from Texas Instruments is a high power-factor preregulator IC designed to provide a low-cost solution for active power factor correction (PFC). This device implements zero-current switched boost conversion, enabling sinusoidal input currents with minimal external components and keeping peak current significantly below that of fully-discontinuous converters.

 

Key features include a power factor greater than 0.99, controlled on-time boost PWM, zero-current switching, and limited peak current. It operates within a frequency range of 200kHz and has a starting current of less than 1mA. The device is specified for an operating temperature range of 0°C to 70°C and requires surface mount.

 

This IC is suitable for low-cost applications in the 50 to 500 watt power range. Protection features include under-voltage lockout, output clamping, peak-current limiting, and maximum-frequency clamping. The UC3852DTR is available in an 8-pin SOIC package.
